    Abstract - (Show below) - (Hide below)

    Explains the procedures for fitting a quadratic, cubic or higher degree polynomial expression to a non-linear set of calibration data, using the least-squares criterion, and of assessing the uncertainty associated with the resulting calibration curve. It considers only the use of polynomials with powers which are integers. In may cases it will be possible to use standard routines available on most computers.
